In an attempt to discover bicyclic compounds containing the 1,2,1,2,2,4-triazine-5-thiones from one pot reaction of arylnitriles with 4-amino-1,2,4-triazine-3-thione-5-one in the presence of potassium tert-butoxide were synthesized.
In the molecule of the title compound, C 5 H 7 N 7 S, the essentially planar triazole ring and the 4-amino-5-mercapto-1,2,4-triazole moiety make a dihedral angle of 70.97 (5) . In the crystal structure, weak intermolecular N-HÁ Á ÁN and N-HÁ Á ÁS hydrogen bonds stabilize the packing.
